IRCT20211016052783N1 IRCT 2022-01-27 Semnan University of Medical Sciences The effect of Muscle Energy Technique on Trismus after third molar surgery The Effect of Muscle Energy Technique on Temporomandibular Joint Motion in People with Trismus of Chewing Muscles due to Third Molar Surgery 2021-12-22 anticipated 48 Complete https://irct.ir/trial/59471 interventional Randomization: Randomized, Blinding: Not blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: In this study, we use the randomized permutation block method for random assignment. The procedure will be as follows: quadruple blocks with a combination of A and B ( group A intervention and group B control ) will be the criteria for action. Given that in quadruple blocks, six different combinations of blocks can exist, a number is assigned to each block (from 1 to 6). The number of blocks is as follows: Block 1: AABB Block 2: BBAA Block 3: ABBA Block 4: BAAB Block 5: ABAB Block 6: BABA Using a table of random numbers, considering the numbers 1 to 6 and deleting the numbers 0, 7, 8 and 9, respectively, the blocks are selected and the way of allocating patients for each of the groups A and B is done according to the selected blocks. Obviously, the list obtained from this method of allocation will be completely random and balanced. After preparing a randomization list for each patient, they will have a number in order of enrollment (from 1 to 48). A sealed envelope is prepared with A or B written inside the envelope based on the compiled list. The researcher, who is not aware of the main list, after registering the patient who entered the study and checking the person's number, takes the relevant envelope and opens it in the patient's bedside and realizes the type of intervention based on the contents of the envelope. In this way, the researcher is not aware of the list and only after the patient entered into the study and finding out if he/she is qualified, he/she realizes the type of intervention by opening the envelope. N/A Trismus following Third Molar Surgery. Intervention 1: Intervention group: Muscle energy technique, In a seated position the subject is asked to open the mouth to its comfortable limit, the operator then placed one hand around the subject's jaw, while the other hand grasped the head for stability, the subject is then asked to attempt open the mouth for 10 seconds against the resistance applied by the operator's hand placed below the jaw, this reciprocal inhibition procedure is repeated five times, After each time, the jaw is moved to a new barrier before repeating the technique. this technique is performed from the first day after surgery daily for seven days. Intervention 2: Control group: They do not receive any intervention. No - There is not a plan to make this available Justification or reason for not sharing IPD is There is no more information.
